Abstract:
Memory effects (ME) in the solid vortex lattice (VL) are observed in a wide range of superconducting materials. Experiments in twinned Y Ba 2Cu3O7 (YBCO) crystals in a DC magnetic field, tilted with respect to the twin planes, indicate that ME in these samples cannot be ascribed to an equilibration process. However, the extense of this behavior has not been explored so far. In this work, we study the role of correlated defects in ME by performing angular ac susceptibility measurements in YBCO crystals. We conclude that when uncorrelated disorder prevails, either in twinned or untwinned samples, ME have its origin in the oscillatory character of the vortex dynamics.
